During the twentieth century there were several cycles of fear of global warming followed about 20 years later by predictions of another ice age. Now predictions of another ice age are being made on schedule after the prediction of runaway global warming originating in about 1988. The ice age fears are supported by recent dramatic drop in temperatures. Those who favor the AGW hypothesis claim the the precautionary principle dictates that we should reduce fossil fuel consumption just in case the AGW hypothesis is true. But, what if there is another ice age starting? In that case, wouldn't the precautionary principle require that we start developing all of the energy sources we can. And, we should start storing food, because it is hard to raise crops in Canada and Russia when they are covered in ice. Intergalactic periods such as the one the earth is currently in usually last less than 12,000 years, the length of the current intergalactic.)
